SPECIFICATION forming part of Letters Patent'No. 633,802, dated September V26, 1899.

To a/ZZ wiz/0m it 11i/nay concern:

Be it known that I, JOHN CEnAns'rnoM, a citizen of the-United States, residing in the city and State of New York, have invented new and useful Improvements in Apparatus for Dispensing Aerated Liquids, which are fully set forth in the following specification.

This invention relatesto apparatus for dispensing aerated liquids, and is an improve*- Inent on the apparatus disclosed iu United States Letters Patent No. 476,760, granted June 7, 1892, toPanchaud and Temple.

The particular objects of the present in vention are to improve the valve, rendering it tighter, more lasting, and more easily fastened; to adapt the'apparatus for use with soda-water fountains, where it is desirable to stir up the Havering-Syrups, and to provide certain other features of improvement, as hereinafterset forth. j

Owing to the pressure of the conn'ed gas it is necessary that all joints, in particular that formed by meeting surfaces of the 'valve and valve-seat, be as tight as possible. EX#

perience shows, however, that when the valve is crowded down closely upon the valve-seat there ensues, owing to attrition, a disintegrationrand disruption of the surface of the washer on the face of the valve that is particularly noticeable along the edges of the slots shown in Fig. 4of the patent and marked 7o andi). This difficulty is overcome in the present invention by locating the transverse passage-ways of the valve within the metal, while the washer has instead of slots merely the necessary perforations, thus reducing the extent of edge which forms the weak portion of the washer heretofore used. It is found more convenient and better results can be obtained by locating the washer in an anguveution comprises an auxiliary tightener by which, after the block is screwed down, the

valve itself 'may be tightened or losened without the aid of any other tool.

Again, the patented invention discharges the contents of its intermediate receptacle intothe `drinkingglass placed to receive it atuone gulp, as it were, through the aperture h, Figs. 1 and 2, of the patent. It is desirable in soda-water fountains to make provision for a needle-like stream first that stirs up the fiavoringsyrups in the botten of the drinking vessel and uthen the larger stream that containsthe bulk of the aerated liquid. .The present invention allows both of these results to 'be accomplished -at one turn of the operating-handleby providing a comparatively ininute orifice through the plug closing the bottom of the intermediate receptacle.

Referring now to the drawings annexed hereto and made a part of thisy specification, Figure l is a vertical section through the valve-seat, showing the valve in elevation and vthe auxiliary tightener partly broken away. f Fig. 2 is a cross-sectiou of the valve-l seat and a plan of the washer. v Fig. 3 is a bottom plan of the valve 5 and Fig. 4 is a veri tical section through the spring-tube, the hollow piston-rod,and the plug, showing the plugl stem partly in elevation.

A is the valve-seat, in which is located the Vwasher A', preferably of hexagonal outline,

as shown iu Fig. 2. The aperture ct ycommunicates with the reservoir through the passage shown in Fig. l, aperture ct communicates with the intermediate receptacle through' the tube H, and apertures o." a" communicate one directly with the intermediate receptacle and the other with the external atmosphere, all just as shown in the Patent No. 476,760. Valve Bis held in thevalve-seat by block C, screwed into the latter.' `On the bottom of the valvehead is .the radial channel h and the channel h. (Indicated in Fig. 3 by dotted lines.) Metal plate B is secured to the bottom of the valve-head and is provided with apertures b2' valve-seat, but it may be placed in the surface of the valve in place of plate B. The advantage of its present location is that it maybe made larger Without enlarging the other parts; besides the channels b 1J are protected by metal instead of by the washer. The superiority of either' construction over that shown in the patent lies in the fact that the meeting surfaces have apertures merely, instead of elongated slots whose edges are soon disintegrated and worn away. If desired, plate B may be dispensed with and passage-Ways b b made in the piece B, the spirit of the invention lying in covering up the edges of the passage-ways so as to prevent the edges if in the metal from cutting the washer or if in the washer from being worn off.

It is desirable to provide the stop A2 in the valve-seat, and the stops B2 B2 on the valve (see Fig. 3 and dotted lines, Fig. 2) so adjusted as t0 arrest the valve in either of its two operative positions.

The hollow screw D surrounds the shank of the valve and is screwed down into block C, as shown, by means of milled head D. The bottom of D presses upon the offset shoulder E of the valve through the intermediate strong spring-washer E. If for any reason the meeting faces of A and B do not form a tight enough joint, all that is necessary is to turn the head D', and thus press B' more tightly against A. I may provide also `the jam-nut D2.

To adapt t-he apparatus to soda-water fountains, I provide an outlet comparatively smaller than the inlet, whereby While the intermediate receptacleis illinga portion of the liquid may pass immediately into the drinking vessel. A very convenient way of accomplishing this is to cut-one or more longitudinal groovesf in the lower end of plugstem F and provide in plug G an aperture g communicating with f. Vhen the handle of the valve is turned in the proper direction, the liquid passes from the reservoir through passage a, channel b, passage-Way a', and the interior of H and plunger I. All this is just as in the patent, and (as in the patent) the pressure automatically forces the plug into the orifice at the bottom of the intermediate receptacle, after which the receptacle itself if lled; but in the present invention, While this operation is going on, at the same time a comparatively small portion of the liquid passes from the interior of hollow piston-tube I, through groove f and aperture g into the drinking-glass placed to receive it, in the form of a line needle stream that stirs up and thoroughly disseminates the syrup or cream in the bottom of the glass.

To empty the intermediate receptacle, turn the handle of the valve, as in the patent, and the gas escaping, as in the patented apparatus, releases the plug, and the contents of the intermediate receptacle are discharged into the drinking-glass. y The simplicity and ease of manipulation are noteworthy. Turn the handle in one direction and the iine stream is directed into the drinking-glass While the intermediate receptacle is filling up. Turn it back and the glass is filled.

It is obvious that modifications could be made in the details of construction of the several parts of the apparatus and that, if desired, some of the improvements described could be used Without others without in either case departing from the spirit of the invention.

Having thus described my invention, what I claim is In a liquid-dispensing apparatus of the type described, the combination with the closureplug having a perforation opening into the outer air, and the plug-stem having a longitudinal groove communicating with the per foration, the outlet so formed being smaller than the inlet for the liquid, substantially as described. Y

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
